Take the bus to Chifeng Road and enter Line 3. Take Yishan Road to Line 9 and get off at Songjiang University Town. Take 15 road to the gate of Donghua University. There is a stop there. It's the university city loop.

I don't know how long it will take to get to Chifeng Road by bus.

It takes about half an hour from Chifeng Road to Yishan Road. After that, it takes about 8- 15 minutes to connect Yishan Road to Guilin Road. It depends on the road conditions. Traffic jams are frequent. After that, Line 9 takes about 40 minutes to get to the University Town. 15 bus will arrive at the gate of Donghua university in a few minutes.

The total fare is one-way bus around 2 yuan, Chifeng Road to University Town 9- 10 yuan, 15 Road 1-2 yuan.

That is, 12 13 14 or so. It takes about an hour and a half to go one way.
